Title:
MIMO-OFDM TRANSMISSION/RECEPTION METHOD AND APPARATUS, AND COMPUTER READABLE RECORDING MEDIUM
Document Type and Number:
Japanese Patent JP2008072722
Kind Code:
A
Abstract:
To provide a MIMO-OFDM transmission/reception method and apparatus, and to provide a computer readable recording medium.
A MIMO-OFDM receiver feeds back alignment information such as a ranking of power intensity of reception signals at a plurality of receive antennas to a MIMO-OFDM transmitter and in accordance with the feedback information, the MIMO-OFDM transmitters aligns sub-carriers to which data symbols are allocated, respectively, to a plurality of transmit antennas correspondingly. Thus, a specific sub-stream can be transmitted via a transmit antenna with a highest channel gain and as a result, a probability to rightly restore the specific sub-stream becomes extremely high.
